@bekkasan : Bad baby! ;)
Yeah, well, babies and children are always ill, like you´ve said. But better to have that than something much worse!
So next time you´ll visit him you have to wear protective clothing, just take some from work with you.... :D
And then you´ll sit down with him in a green or blue overall under a white op coat with a hair protection, a mask under a visor and gloves of course. Then you spray desinfection all over him, put away all his toys and give him just one new one you´ve bought and desinfected before... shall be safe then...
